現在、携帯電話等の電子装置のハウジングは、殆んどプラスチック或いは金属材料により形成される。金属製ハウジングは機械強度が高いが、金属材料が電磁波を遮蔽（Ｓｈｉｅｌｄ）する性質を有し、高周波（Ｒａｄｉｏ Ｆｒｅｑｕｅｎｃｙ）の送受信を行う携帯電話或いはワイヤレスインターネット（Ｗｉｒｅｌｅｓｓｌｅｓｓ Ｉｎｔｅｒｎｅｔ）機能を有するパソコン等の電子装置に対して、高周波数の要求を満たすことができない。一方、プラスチック製ハウジングは、高周波数に関する要求を満たすが、金属質感に欠ける。 Currently, the housing of an electronic device such as a cellular phone is mostly made of plastic or metal material. The metal housing has high mechanical strength, but the metal material has the property of shielding electromagnetic waves, and it is an electronic device such as a mobile phone that performs transmission and reception of high frequency (Radio Frequency) or a personal computer having a wireless Internet (Wireless Internet) function. The device cannot meet the high frequency requirements. On the other hand, plastic housings meet the requirements for high frequencies but lack a metallic texture.
プラスチック製ハウジングの表面に金属質感を付与するため、通常前記プラスチック製ハウジングに対して真空蒸着処理を行う。しかし、それによるコーティング層が電子装置のハウジングの外面に形成されるため、長時間にわたって使用されると、摩損され易く或いは脱落する恐れがあり、前記ハウジングの外観の美観を損なう。 In order to give a metallic texture to the surface of the plastic housing, a vacuum deposition process is usually performed on the plastic housing. However, since the coating layer is formed on the outer surface of the housing of the electronic device, it may be easily worn away or fall off when used for a long time, and the appearance of the housing is deteriorated.
本発明は、上記の問題点を解消するためのもので、金属の外観効果を有し且つ摩損されにくい電子装置用ハウジング及びその製造方法を提供することを目的とする。 An object of the present invention is to solve the above-described problems, and to provide a housing for an electronic device that has a metal appearance effect and is not easily worn out, and a method for manufacturing the same.

The decorative film includes a transparent plastic thin film, a vacuum deposited layer formed on the surface of the plastic thin film and having a metallic visual effect, a varnish layer formed on the surface of the vacuum deposited layer, and the varnish layer A color layer formed on the surface of the protective layer, a protective layer formed on the surface of the color layer, and a binder layer formed on the surface of the protective layer. The plastic substrate is bonded to the binder layer of the decorative film by injection molding.
また、上記の目的を達成するために、本発明に係る電子装置用ハウジングの製造方法は、透明なプラスチック薄膜と、前記プラスチック薄膜の表面に形成され且つ金属状の視覚効果を有する真空蒸着層と、前記真空蒸着層の表面に形成されるワニス層と、前記ワニス層の表面に形成されるカラー層と、前記カラー層の表面に形成される保護層と、前記保護層の表面に形成されるバインダー層と、を備える加飾膜を用意するステップと、前記加飾膜を所定の形状に裁断するステップと、上記成形された加飾膜を射出成形金型内にセットして、前記射出成形金型のキャビティに溶融状態のプラスチックを射出注入して、前記加飾膜のバインダー層に接合されるプラスチック基体を成形するステップと、を備える。 In order to achieve the above object, a method of manufacturing a housing for an electronic device according to the present invention includes a transparent plastic thin film, and a vacuum deposited layer formed on the surface of the plastic thin film and having a metallic visual effect.

Since the vacuum deposition layer 23 is formed as a non-conductive and discontinuous film, the high frequency transmission / reception function of the electronic device employing the electronic device housing 100 is not limited. The vacuum deposition layer 23 has light transmittance and a metallic appearance effect. The material for forming the vacuum deposition layer 23 is a metal such as tin (Sn), indium (In), or an alloy thereof, or a non-metallic material such as silica (SiO 2) having a metallic appearance, aluminum oxide, or the like. can do. The vacuum deposition layer 23 can be formed by sputtering or vacuum deposition. In the embodiment of the present invention, a sputtering method is employed.

The color layer 26 is formed on the back surface of the varnish layer 25 and is made of ink, and gives an appearance color to the electronic device housing 100. The protective layer 27 is formed on the back surface of the color layer 26 and is made of ink, and is used to protect the color layer 26. The binder layer 28 is formed on the back surface of the protective layer 27 and is used to enhance the bonding force between the decorative film 20 and the plastic substrate 10. The binder layer 28 is made of a binder such as an epoxy resin, a polyurethane resin, or an acrylate resin.
前記プラスチック基体１０は、射出成形により前記加飾膜２０のバインダー層２８に接合される。これにより、前記真空蒸着層２３、前記ワニス層２５、前記カラー層２６、前記保護層２７及び前記バインダー層２８は、前記プラスチック基体１０と前記プラスチック薄膜２１との間に位置する。 The plastic substrate 10 is bonded to the binder layer 28 of the decorative film 20 by injection molding.
